Veteran television game show host Bob Barker was taken to a hospital emergency room in Washington on Thursday, apparently suffering from exhaustion, his Los Angeles publicist said.

The 75-year-old host of "The Price Is Right" was in good condition but will remain in George Washington University Hospital for tests until this afternoon, his publicist, Henri Bollinger, said in a statement.

Barker, who has hosted the popular game show for 25 years, was in Washington for a breakfast meeting with members of Congress to seek support for the proposed Captive Elephant Accident Prevention Act.

The legislation is one of the favorite causes for Barker, a noted animal rights activist. The measure is intended to stop mistreatment of elephants in circuses.

In a statement issued by Bollinger, Barker said: "I am disappointed not to have been able to attend the meeting. I've been working with thousands of people across the country to protect elephants from the horrors of circuses. This is a serious problem."

Before joining "The Price Is Right," Barker hosted "Truth or Consequences" for 18 years.
